Stellaris Focuses on Improving Game Performance Amid Challenges

03 Oct 2025

In the ever-evolving universe of Stellaris, a paradox of technical challenges and innovative expansions emerges, as the game's latest DLC, Shadows of the Shroud, faces significant criticism. Despite the expansion's imaginative exploration of Psionic Ascension and complex new factions, players are voicing concerns over persistent bugs, game instability, and notably, poor performance.

Emphasis on Performance

Stephen 'Eladrin' Muray, Stellaris' game director, articulated the team's staunch commitment to addressing these performance issues, designating it as the 'highest priority'. However, Muray also tempered expectations, describing the road to recovery as a 'long haul'. In response, a 4.1.5 open beta version has been launched as the 4.1.4 failed to deliver satisfactory results.

A dedicated subteam within Paradox is investigating critical aspects affecting the game's performance. Key targets include the application of modifiers, impacts of fleet counts, and the user interface. Additionally, the team aims to balance the economic aspects driving these issues. Muray revealed their discovery of an abnormally high number of ships in late-game saves, which were traced back to stronger post-4.0 economies.

This discovery has significant implications for late-game performance, which sees a marked divergence compared to earlier versions, such as 3.14. The developers are generating numerous save files to delve deeper into these disparities and pinpoint root causes effectively.

Strategies for Improvement

Proposed solutions from the Stellaris team involve a multifaceted approach. They intend to reduce ship numbers through a combination of economic rebalancing and mechanical alterations, along with making enhancements on the client side. For instance, rewriting modifier calculations, despite being a risky endeavor, has been initiated to bolster late-game functionality. Muray proposes boosting ship cost and power tenfold to decrease overall ship counts while introducing more advanced, economically demanded hulls to maintain the game's strategic depth.

On the economic front, the team plans to limit the post-4.0 growth and mitigate excessive feedback loops that deviate from expected baselines, thus restoring equilibrium. In multiplayer contexts, addressing stability issues and desyncs is crucial. Muray encourages players to actively report bugs to expedite fixes.

Gosia, a quality assurance analyst, highlighted that performance testing is being conducted rigorously across a range of system specifications, continuing efforts initiated prior to the release of version 4.0. This underscores the developers' resolve in enhancing the gaming experience of Stellaris, working diligently to remedy the challenges currently besieging the much-admired spacefaring simulator.
